According to [this comment](https://github.com/pydata/xarray/issues/5172#issuecomment-823298453), the underlying issue discussed above should be resolved with `h5netcdf >= 0.11.0`. Here's a notebook I ran today for `dataset = 'IPSL-CM6A-LR.abrupt-4xCO2.r1i1p1f1.Lmon.cLeaf.gr'` with `h5netcdf == 0.11.0`:...
